Raincoats are much cheaper than cars.

It is just… rain? I’m very confused if I’ll be honest. Your jacket gets wet, or you carry an umbrella so you stay dry? It rains 7-8 months of the year here, I genuinely never thought of it as a reason to drive so might be the wrong person to answer. As long as I’m not drenched (never happens unless i’m out for a rainy run on purpose), who cares the jacket will dry once I get in.

I've heard "some people use their 2 ton car as a rain jacket" and thought it was urbanist hyperbole, but here you are.
